CMake Fortran is broken on Ubuntu Linux

[derobins]

The Fortran ftest test fails on Ubuntu Linux 22.04.3 w/ gfortran 11.4.0. It passes on the Autotools. The Fortran interface has problems due to the way we jam 64-bit addresses into 32-bit Fortran integers, but we should investigate this since it works on the Autotools. We'll at least want to understand the problem.
